摘 要：BACKGROUND In most cases,it is not difficult to differentiate common bile duct(CBD)stone from Ascaris infection because they are different disease entities and have different imaging *** two diseases usually demonstrate unique characteristic findings on computed tomography or magnetic resonance ***,we report a rare case from our experience in which a CBD stone mimicked and was misdiagnosed as *** SUMMARY A 72-year-old male presented with elevated serum liver *** tomography showed a hyper-attenuated,elongated lesion in the CBD lumen and associated biliary *** resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography revealed a linear filling defect in the bile ***,elongated echogenic material with a central hypoechogenic area was seen on endoscopic *** the imaging findings caused us to suspect infection with the nematode Ascaris,the lesion was revealed to be a dark-brown-colored CBD stone through endoscopic *** We report a rare case of a CBD stone that mimicked *** also review the literature for side-by-side comparisons of the imaging features of CBD stones and ascariasis.
